Developing quasi-solid-state electrolytes (QSSEs) with excellent electrochemical stability at high voltage can improve the properties of the SDIBs, said a recent paper published in the journal of Advanced Functional Materials.
The researchers from the Shenzhen Institutes of Advanced Technology of the CAS developed a flexible SDIB based on a QSSE, which exhibits a porous 3D structure with apparently enhanced ionic conductivity, facilitating fast ionic migration of both anions and cations.
The SDIB showed excellent cycling stability with a capacity retention of more than 90 percent after 600 cycles, high flexibility and a wide working temperature range from minus 20 degrees Celsius to 70 degrees Celsius, said the paper.
The results suggested the potential of the batteries for high-performance flexible energy storage applications. (Xinhua)
A research team led by Prof. ZHANG Huamin, Prof. LI Xianfeng and Associate Prof. ZHANG Hongzhang in Dalian Institute of Chemical Physics proposed a new lithium-sulfur (Li-S) battery electrolyte to achieve a high energy density Li-S battery with a longer cycle life.
Recently, a research team from Qingdao Institute of Bioenergy and Bioprocess Technology exploited a new type of organic magnesium borate based electrolyte which was synthesized via a facile in-situ reaction of tris(hexafluoroisopropyl)borate [B(HFP)3], MgCl2 and Mg powders in 1,2-dimethoxyethane (DME).
